I-20 driver vs 910D2 driver. Which one is a better deal?

I am currently playing a Ping G-15 driver 10.5* draw driver and cant say i dont like the thing.  I hit is as good as I can hit any for how long iv been playing but i'm a craigslist junkie and cant help myself.  This driver came with a complete set of ping clubs I bought off craigslist a few months ago and there a couple interesting deals currently at my feet and want to get some opinions.  I got a few extra dollars burning a hole in my pocket and I have the option of buying an almost new Ping I-20 9.5* driver with project X shaft for 225$ (possibly a couple dollar negotiating room) or a Titleist 910D2 9.5* with an Aldila RIP shaft for 195$.  Are either of these deals worth jumping on?  If so which one would you go for?  Or should I just keep playing my Ping G-15 and spend my money on beverages ?

I currently play a 910D2 and have to say, it's the best driver I've ever used, they're expensive so grab it at a good price if you can !

Based on your handicap "alot" you may want to go with the most forgiving, G15. The 910D2 would be more forgiving than the I-20.

Yeah, can't speak about the D-2, but the I-20 would be too much for most high handicappers to handle.

Thanks for the information guys.  I didnt know that there was a big difference between the I series and G series drivers.  I might see if I can talk the guy selling the titleist driver down at all this weekend and maybe pick it up if I can.  The more people I talk to the more good things I hear about the 910D2.

A driver is like a pair of shoes.  Find one that fits you and you don't mind looking at in your bag.
