My personal way of choice right now is build some MPS armor, put gliders, as well as the jump upgrade on it, and keep things reasonably light. Depending on which sets of crafting recipes you have enabled for MPS (Vanilla seems easiest, some of the parts can be a bit expensive with IC2 recipes), this can get a bit expensive iron-wise since a servo takes 10 refined iron by my count. But being able to glide effortlessly between islands and stuff is just so fun, and it makes covering distance a lot easier.
You may want to get some cinderpearls anyways, since heat doesn't dissipate naturally in the nether, and a cooling system needs 4 eyes of ender.
