Out of those I would either go for the R5 or the X460. Both are great clubs and both as equally as forgiving. Out of the two, the R5 can be had for about $100 cheaper than the X460 and imo performs just as well. The launcher Ti460 didn't fit me well so I didn't care for it much and ended up selling it. Also, do a search on drivers, there are lots of topics and opinions on the various drivers out there plus a review section
The Cleveland Launcher 460 for $150 is a darned good buy. I don't think you will in reality do much better with any other driver, except to spend more money. I still play a Launcher 330, and I have hit the 400 and 460 also. The only difference I can see or feel is that the larger club head is a bit more forgiving. But I love my older 330. If I ever replace it, I'm pretty sure a Launcher 460 is what I will get.
I have been using the Cleveland Launcher 460 for the past year, or so. I love it.
When I went looking for a new driver I demoed 5 drivers. My choice was the Cleveland. I am not disappointed, but that is me. It can be a matter of individual preference.
From the ones that you listed the R5 is the best and most forgiving. However if your thinking about spending $300 on the Callaway go hit the Nike SQ. the SQ is the best driver out there right now.
I am going to the golf store tomorrow!
Today at the range I was hitting my Great big bertha and the head just flew off!
Guess it was a sign from God...
