Yeah as much as I hate to agree (not because I don't love you boys) because I too would like to never come off:bb3:
However, I have to agree with the above. I also seem to be an advocate of lowering doses on cycle like you mentioned (btw pm me or let me know here where and who you got your info on the taper idea from if you would, I'd like to know). Still look at what you're suggesting. You're going to taper down you test dose and your ai along side it wait till you feel nice and recovered. Then go back on another AAS right away? C'mon man! You know that not really a great idea. Yes it sucks.
IMO you'd be just a good with doing what you described and then using something like the following powerfull, symetry, anagen, cissus, junglewarfare( about to start it soon but I do trust ALRI alot and don't think they'd put out a **** product) rebound reloaded (we'll have to see but you get the point), maybe some retain ect. I've done the anavar bridge before sort of. By sort of I mean I did it in the same way you seem to be describing it. Meaning,I used it as you describe to "solidify" my gains. It worked pretty well. I lost some of my water weight then hardened up alot got a little more vascular (this was at a girly dose of 20mg a day any more and IMO you're not tappering you're doing a var only cycle). I then went off of it after about 1 1/2 months and took a nice long break from AAS (like 5-6 months). THAT'S NOT REALLY A BRIDGE THOUGH IS IT? A bridge means I would have used var to "bridge" onto another cycle, at least that's the impression I'm under.
Anyway, I've done that before and all it really is (as your decribing it I think) is extending your taper but using var instead of test and your ai. Honestly, I think that if you use a nice little stack of some of the products I mentioned about you can do JUST FINE to say the least in place of var.
