Brian,

I am by no means an expert but here goes. The letters L A R and S refer to the flex of the shaft. L=ladies, A=seniors, R=regular and S= stiff. These reference the amount of flex each shaft has ie. S for stiff doesn't bend very much and is usually for players with a fast swing speed while the L is for the ladies who "usually" have slower swing speeds so the shaft flexes and whips more to give them more length and height. The other two, A and R are usually for men. The A as I said is for seniors (older men with slower swing speeds) while the R is for men with somewhat faster swing speeds but not really fast swing speeds. You can check with your club fitter or club pro as to what speeds fall into what category as some fitters/pros vary as to the speeds that they use for each flex.

Now as to the loft degrees. If you check this site you will see a heading entitled "clubs". Within that heading you can pick out the TS2 that you referred to (driver, fairway, or hybrid) and that will give you the loft specs for each version. Once you have those numbers you can pick whatever iron you are considering and the site will lead you to the specs for each of the irons ( 3,4,5,6) that you want. Then just compare the lofts.

Just keep in mind though that if you are trying to compare the irons to a hybrid (my guess as to what you are asking about) the hybrids are longer so they will be different in the distances you hit them ( a 25* hybrid will go further than a 25* or 26* 5 or 6 iron). So again I will suggest (as will just about everyone else on this site) that you see a certified fitter or your club pro and let them work with you and your swing to get the proper clubs for your game.

Fairways and greens to you.

Not sure I totally understand your first question unless you want to know how a 15 degree TS2 Fairway wood performs compared to a 20 degree T300 4 iron? They would never be "equivalent" as even if they had the same degrees of loft, the shaft length would be different and the center of gravity different. You really need to factor in total distances, gaps, and trajectory as you build the 14 club set that works best for you. Some people like long irons and others gravitate to more fairway woods and hybrids. On the second part; (L) is ladies or light, (A) is seniors, (R) is regular, and (S) is stiff. Those are common categories of flex in the shafts form most flexible to least flexible. A club fitter will measure your swing speed and tempo using technology like TrackMan and recommend a flex best suited to give you maximum distance and control. Suggest everyone get properly fit and not buy off-the-shelf unless you know for sure what you need.

OP:

It has been my experience that when I replace a longer iron with a hybrid with similar loft the hybrid flies higher and longer than the iron it replaced. The only way to know for sure what hybrid to replace an iron with is to take them out and hit them.
