@Fox; I went to TI after RB had some 10x and under pots and it made no diffrence at all, even trained in the 150 area. I had almost a stack of voucher i receieved for my birthday from my sister and some i also saved up just waiting for rebirth that was like 10 or 11 days worth. Yes i rb'd at 199 so i was 100 rb, regardless of my lvl i still found it pointless withen those days even going only on double exp days i only managed to get about less than 6 lvl. I really don't think TI is worth it at all.

So personally i'd recommend just going to rome or sharks. be in a team and 24/7 train if you are able you'll get more out of it. save pots for exp days only so you get the most of them. if you can and are fast enough without using items (cause you don't want them to break) then i suggest debuffing you always get more from deuffing.

But if you already happen to have the vouchers then go ahead and use em. like i also mentioned above save them for expdays so you get the most out of them... though if you have to better to get them free than wasting money on them. perhaos if you RB at 180 and are 81r (so its lower lvl) you may get more out of it then i ever did.
