I acquired seven TaylorMade SLDR 57g senior iron shafts, 41.5″, no trimming instructions included.  I am building 5 thru GW with Adams XTD heads for a left-handed 75 yr old.  He is a former professional tennis player and a good athlete.  He usually shoots even to 4 over on our local 3200yd 9-hole track.  He would like the clubs to be as stiff as possible.  How should I tip trim the shafts to achieve this?
