vlsd vs hlsd

[nlzmo400r]

Ok guys, i know these two things have been beaten to death, but I've gotta ask. Everyone on here that has an hlsd, says taht vlsd's are garbage. I know that a good s15 hlsd going to lock harder than a stock s13 vlsd. However, i hear that the s15 diff will only split torque 75/25. I dont drift, all i do is autoX and the occasional road race. It seems that for autoX, i would need more than a 25percent power to the outside wheel, especially being as tehre are a lot of 90degree turns in autoX. Would it be worth it for a 'non drifter' to invest $6oo-7oo for an s15 hsld? Or should i just get the vlsd for $300. Spending 1k on a kaaz or quafie is out of the question. Any suggestions?
