The 6/8SE tripod is not the same as that used by the SLT, the SE has thicker legs and the interface with the mount itself is different. The SE tripod has a thick metal plate at the top with three thumbscrews which lock the mount into place (with rubber pads on the bottom of the mount). The SLT uses a ring and large central nut. The SE mount is perfect for the 6" SCT but I agree that it's undercounted for the 8", although it can be somewhat mitigated by the anti vibration pads and/or a motorised focuser and/or a very light touch
It'll be interesting to hear if the Evo is a big improvement for the 8"...I suspect it would be, if they're brave enough to sell it with a 9.25", which is a lot bigger and heavier than the 8" and no doubt the 9 is undermounted
