According to that interview: http://www.pbnation.com/showthread.php?t=3843821
Soft tip bolt = better on fragile paint, less efficient
Full metal bolt = more efficient, less good with fragile paint
Few things I would like to discuss:
1a.Why is it less efficient? weight of the bolt or air flow design or friction (due to soft tip touching other parts)
1b.If its weight, why not making a lighter bolt?
1c.If its air flow design, why not making the 2 bolts with the same airflow design?
1d.If its friction, then why making a 'bad' design? (if one is better then the other, there is a bad design)
2.Being better on fragile paint is not very hard to mesure, so I wonder how much better? Can PE share some stats regarding this?
ex: Out of 20 random box/brand/etc, soft bolt is breaking 5% less paint....
3.a Alignement of the cavity on the tip of the softbolt, do we care?
3.b If we do, I wonder if it would be possible to make an oval bolt so it stays always aligned...
(oval or any kinda of shape that would automatically aligned the cavity)
4. I believe I can dwell tune lower with the full metal bolt, do you guys are noticing that too? (both bolt with approx the same amount of shots count)
