Hi: I recently purchased T300 Irons 5-P. I use 718 T-MB 3 and 4 iron, which I hit well. I am seeing now that the T300 5 iron and the 718 T-MB have the same loft of 23. What would then be the difference in how far I would hit each club being they have the same loft? Wondering if I need to carry both. Please let me know. Thanks!
