I am surprised that you opted for the bass drum mounted toms. You don't see a lot of that these days.
I would go with the 8" Tom but of course it's up to you.
The main reason I would go with the 14" floor tom is that the SQ2's amazing shell sound would get entirely lost in the smallish 8 " shell. If need be, get the 8 later. Or as someone else said, get both.
BTW, that is an unusual looking bass drum tom mount. As long as it functions great, that's all that matters.

Does the bass drum tom mount system add a lot of weight? I have no doubt about its functionality & build quality. but I'd want to be able to lift it on a gig!!
Well that depends on the wood and the shell thickness you choose, doesn't it!SQ2's are not too light to begin with.
