I think it would only really be appropriate or effective for certain high-submit cats like teen, amateur, big tits, mature, etc. You'd be inviting problems with the recips though...the only small advantage in that case may be that the niche link in your recip would turn the link trade into two one-way links that are still relevant if you change the category but still let it fly. Me, I want to see you with a softcore gangbang cat
