do you want a softer riser or hard ones? Indy risers work in Aces, but I've used bones too, they have the slider instead of the holes. I have some krooked risers on ventures right now, they fit perfectly and they're kind of soft.
Hard.
I guess Indy risers work in Aces, but the Ace baseplate is smaller than the Indy baseplate so the risers stick out quite a bit more than on Indy. I was thinking if something is a tad bit smaller, so it doesn't stick out so much. I'm afraid the Indy riser would break as it sticks out so much that you can partially see the square holes on the riser as the Ace baseplate doesn't cover it all that well.
As for Ventures, I've never had any but am interested in getting a pair and I have no idea what the baseplate is like. With Thunders the screw holes are more centred right, so you gotta use risers with those long slots to get the riser to align correctly?
I have to order all this shit online, so I'd like to get it right the first time. Would be easy to see what fits in a shop, but sadly I don't have that luxury.
