Hi, first post here.

I have just bought a set 3 to pw ap1 710 with dg s300sl shafts.

I am a tall bugger at 6'6' currently play 1" longer R300 and really like that lenght, the r300 were simply butt extended and still do play pretty well. I hit my current Letters t9 7i a consistent 135m

I would really like 1" longer in my aps and would like a little feed back before I go ahead.

My plan is to install a 2i shaft into the 3i and work down from there, this will soften the s330sl a bit? if so that may well be pretty nice for my swing.

Will this give me 1/2" longer in each club ?

If so I would like to use high end 1/2" extension in the butt to finish them at 1" longer.

I cannot afford to buy a full set of un cut shafts so this option really apeals to me, I intend to also spine alighn the shafts during the rebuild and use new crossline midsize grips.

I feel this will give me a good soultion to my needs and play pretty sweet at a gap between a dg300 stiff and dg300 regular.

 I do wonder how it will affect the swing weight?

Can't wait to get them in my bag.

1 last thing, what does the 710 mean? model / steel used?

Thanks very much
