Ace,
I have the ProHunter with the FlexTech stock in .243 caliber. The flextech stock has the limbsaver pad built in to the stock. I still can't "watch the shot impact"....even when I shoot 70 grain bullets. I know the forarm on the prohunter is the plastic lightweight one, so maybe a heavier one would help....but then, my Contender rifle in .223 has a long wood forarm and wood stock. With the .223 it's a sometimes I can, and sometimes I can't.
So...to answer your question, if the only purpose was to help "see the shot", I don't think I'd make the investment.
MHO
