I saw sub 85 today on myspygolf

I would consider that speed moderate. Mine is in the same area as yours and I immediately thought this driver might be for me. I have the TS2 3-wood and absolutely smoke it so I’ve been interested in hitting that driver but now this TS1 has my interest

Same here. Same sewing speed and same TS2 driver. The TS2 has been the best so far but I will leap at the opportunity to buy the TS1 if it helps. Would be nice if Titleist Staff members could provide input.

I always find the shaft makes the most difference. Dialing in the proper shaft would benefit the most. The head difference will help a little but if it’s not in the right shaft it won’t matter anyway. There has to be a fitter with both heads and the same shaft to try out. I got a TS3 with a Kuro Kage 60x just to try it and I didn’t like the driver. Put in my trusty 70x white board and I love it. Just my experience.

I agree with this, I use a Fujikura Speeder 757 Evo II still because of how well I hit driver heads with it compared to newer shafts.

Wow thats interesting, great question! Moderate swing speed seems 80-90 ish. thats a pretty good idea by the people at titleist, theres probably a lot more "moderate" swing speeds out there than there are fast. Interested to see how these are performing

While I'm in the range of "less than 220 yards" even with a TS2, I will need to trial to see if the 45 g lighter TS1 results in an increase in club head speed. To gain speed, I need to weight transfer and hip rotation faster as well as having a lighter club. If my late 60's body is up to it, I'd love to get 8-10 more yards with a TS1. This is an interesting addition to the Titleist line geared more to serious golfers at average physicality.

Also weigh the fact that the lighter club might be a bit harder to control. You won't really know until you play with it for a while. If you want 10 more yards but you already have trouble with hitting fairways, be careful you don't fix one problem only to have another problem. When i moved from 917D2 to TS3 not only did i pick up a few yards, the shaft i now use is helping with the severity of the off line hits. On courses with thick rough, this is much more important to me than 5 yards further down.

Have been playing TS2 with 65 gram regular flex shaft, at 65 years young, with 80-85 swing speed. TS2 carries 200 yards. Today tried the TS1 with Fujikura Air Speeder 40 gram regular flex. The ball was launched considerably higher, and as mention above seemed to loose a few. Still testing, will get on Trackman Friday and compare TS1 TS2.

Please post more of your results - and Trackman details if you get them. I'm still negotiating a fitting date with my go-to pro to see what happens. I have a TS2 that is the best driver I've had for me, but 8 yards or more is tempting. I don't often get to use my middle irons but 10-15 yards would change that.

A 40 gram shaft works real good for me. Try it and don't be afraid of change if it helps your game.

This driver is launched in the UK on 28th June, will be trying out then and hope it's what I,m looking for, also interested to know if they will be having dedicated fairway metals of the same lightness.

I agree 100% with all the comments that speak to the correct shaft! With today's technology it is sometimes hard to separate the heads, but for me the shaft difference is almost immediate. Sometimes I don't even have to swing it to know what it is going to play like.

I've read some great comments in this forum with respect to heads, shaft combinations in an effort to attain maximum club head speed.I like Dale's comment about being careful not to fix one problem and have another pop up.One thing to consider, Are you a "smooth" swinger of the club? Initially I bought into the "lighter shaft helps generate more speed " argument, but as I found out, I'm not a smooth swinger and I don't have a one plane golf swing.I'm inside early, loop the club to get back into position and load very late in the downswing. The best driver shafts for me have been in the 75-80 gram range,stiff with minimal torque.When I use a light shaft, I'm too fast at the bottom, and I can't square the face, resulting in blocking the ball all the time.
Take some stock in your tempo when making a decision about heads and shafts. Good Luck.
