I haven't used either of the toppers you mentioned. All I can say about that is that the Provari only has a 510 connection, so if your toppers are ego threaded, you need to also order a 510 to ego adapter when you place your order. As for batteries, if you just have two, you may wish you had ordered more. My Provari is the full-sized version, and I'm always charging two batteries for several hours every night. I have four and rotate them.
And congratulations! I think you'll love the performance of the Provari. If you don't, they have great resale value.
