It can certainly spoil it end up deciding whether to fish absurdly heavy or get snapped off regularly, I've started kids off on a whip and landed 8lb carp whilst letting them bag up on tiddlers, but I don't know where I'd take them for tench tbh, bit young for the river but will find then a carp free water next year , they're having a taster on the fly fishing atm...but I'm not spunking £300 on them until they beg to go, rather play football most days lol,
