tsn is a lot less bulky but will gain length about the same (in nature tsn is a longer fish than rtc) but they both have spurts so one my race ahead then not seem to grow at all for a while.
it depends on which species of shovel nose you have. some get really big and others about a foot. go on a website for buckhorn crates. 1800 543 4454. they have huge plastic crates that make awsome fish takes. especially good for housing monster fish while you are saving for a big tank.
