The best spinner in UU is kabutops as an anti-lead
OK really though, I'd say hitmontop is the best spinner as he has a nice combination of bulk (especially on the special side) and the ability to also spin while running technitop and becoming a nice offensive force at the same time.
if something like froslass is setting up spikes later in the game though in my opinion it's better to just bring out a pokemon that resists ice that can throw out a powerful hit or set up to deal with whatever comes in (kabutops again can sponge hits and set up rain/SD for itself while definitely scaring off froslass with the threat of stone edge, azumarill can come in and fire off a cb waterfall or put up a sub, relicanth can run rock polish and go for a sweep with LO or lum while scaring it off with head smash, etc.). I know the strategy of dual spinblocking is relatively uncommon, but dual spinning is even more uncommon...but in theory it would work the best (running kabutops as a rapid spin anti-lead and foresight hitmontop to beat dumb crap like spiritomb), then running bulkier pokemon who benefit from not having their health slashed every time they come in like slowbro as well as stuff like moltres/altaria who obviously like not having sr up on the field.
Speaking of that, is this a set idea that might be workable in UU?
Spiritomb @ Leftovers
252 HP/252 Def/4 SpAtk
Bold Nature
Calm Mind
Taunt
Rest/Pain Split/Shadow Ball
Dark Pulse/HP Fighting
Taunt would keep you from getting phazed and dealing with switch-ins who would try to set up or taunt you themselves like drapion. With spiritomb's bulk helped by CM, you would be safe to spam taunt expecting a switch or just setting up further or attacking the switch-in. The potential advantage of this is that you can catch a hitmontop as it switches in with taunt, rendering it completely useless. Lack of recovery is a problem, but it could run rest if it needed to. Pain split is secondary, but taunt would force switches and give it time to recover with it. It could also go for coverage and the recovery problem could be fixed by pairing it with a support clefable (or even a bulky drummer to threaten from both the physical and special side) and slowbro to spread paralysis and tank fighting hits. That could be lots of fun =D
Again, haze milotic would be a problem...but only if you didn't taunt it as it switched in. A lot of things that traditionally run toxic (bulky waters, bulky grass types, etc.) would also be directly lured into slowbro's thunder wave, meaning that they would all be easily taunted and set up on/stalled out via pressure so that sounds like a nice theorymon set to me
