Pfunk123,

The heads on the x-18s are great and the CW shafts(112 grams) are so so. You should be using the lightest, most flexible shaft you can control. Also, the heads can be bent outside the factory. Low hosel bending is available outside the factory, but be careful of who you use. The proper bending bar and clamping machine are required. Here are a couple shaft suggestions:
Grafalloy ProCustom (74 grams) a good affordable graphite shaft.
TrueTemper TX-90 (104 grams) a ultralight steel shaft for.
Both are readily available for around $11 each shaft.

A decent reshafting person worth their weight will be able to reuse the grips.

Hope this helps.
