The Blue along with the Prolite and ProLaunch are Grafalloy's engineered shaft design for today's big golf club heads. Specs on the Blue make it an excellent choice for all handicappers who wish to maximize distance and accuracy with a low torque/ mid bend ultralite shaft. What does that mean?
The Blue weighs in at only 63 grams...very light. Mid bend means mid launch...low bend would be high launch...if you want that you need to check out Grafalloy Prolaunch. High bend translates to low boring launch and you want Grafalloy Prolite 3.5. Torque on Blue is a ultralow 2.8.
Flex options on Blue include R, S and X. Grafalloy provides fit assistance on their web page. But in general, a good rule of thumb that I find lines up pretty well with my launch monitor is what club do you use 150 yards out? This will give you a fair idea of your club head speed which translates into what flex you need. Not the greatest once in a lifetime shot you had last summer....what club can you count on to reach the green at 150 yards? If that club is a 5 iron you need an R flex. 6 iron is the breaking point, you may want an R flex driver if you hit a 6 iron just barely 150. If you are comfortable with a 7 iron? Think S flex for your driver and woods. 8 too if it's really maxing out. 9 iron or wedge? you need an X and I'm wondering why you aren't on tour.
Spine alignment or having a shaft, "pured", is greatly in vogue these days. What is it? and do I need it? Golf shafts all have a dominant point that they will naturally return to when subjected to load or twist. Spine alignment is based upon locating that natural point and aligning the club face to take advantage of the shafts tendency to return to it. I'm a believer because I've experimented with random OEM alignment and then aligned the same club..same shaft. The result is amazing.
You can order SST pured shafts which will come with a mark you can align yourself from most of the big golf clubmakers supply. Usually runs 10 bucks a shaft. Or, find your local clubmaker. I've yet to encounter one that either twangs, (clubmaker slang for aligning while epoxy is fresh), or knows someone who does. Or, didn't you always want to build your own clubs anyway? You can get spine alignment tools on Ebay for less than $50...and clubbuilding is fun!
Blue compares nicely to high end shafts for low weight, lower torque than most and mid launch. Blue's price new from a catalog will run $60 plus. On Ebay? you can do better. Blue is in the same price range as Aldila NV and compares nicely. If you can find G Loomis ultralite, (Aldila bought them out a few years ago), you can get a real bargain with a very comparable shaft.
