So pretty sure I know the answer but wanted to get some opinions.  I have a few sets of irons and want to narrow down to just one of them for next year and quit switching around.  I was playing srxn zx5 and PXG 0311P.  Then I recently picked up a set of T300 from 2019 in great condition with my favorite shafts in them.  I was a 15 handicap last year but due to some issues I am now a 20 and getting over hip replacement.  Yesterday I played the t300’s and really liked the way I hit them.  Now being a 20 my swing is not consistent at all.  My goal is to get to a low teen handicap next year.  Are the t300 too much game improvement to get to that level?  Should I just play more of a players distance iron and work on getting better with it or stick with the t300 and dump the rest?  By the way I will be 62 in a couple weeks and hit my 7 iron 135.   Thankd
