id sell the old ta and build up the 25th ani one
the price has started to fall on ta's so i would sell it while u can and still get a good price
as for sticking them in the loft will any one want them in a few years ? will they be worth anything?
a lot of people have got back into bmx that are in there 30-40s me included but give it a few years i think the bubble will burst and hardly anyone will be interested again
build the new one and ride it
