I'm coming round to the idea of sausage gloves, always worn splits, but recent offerings are starting to sway me.
SS Max Powers, Kook Recoil 900's and a few others are nicely pre curved, and a lot of the top end gloves are flexible enough for me to consider them.
Split finger was always my choice previously because of the flexibility and the light weight nature of the gloves.
However, I'm trying to play a lot straighter, with my top hand being really dominant, to the point where I'm holding the handle with just my thumb, forefinger and middle finger on my bottom hand. Sausage finger gloves promote this because they are less flexible, so my natural instincts to grasp the handle like a fat kid gripping a hot dog are suppressed.
