prices are similar. the hellraiser comes with an 81-7/85-7 set, the loomis 707's. other than that some slight material differences here and there but the specs are close enough that its a looks contest for me.
also post any other mean looking lefty 7 options.
I suppose it comes down to if you prefer a maple or rosewood board & which one you prefer the overall aesthetics of. It'll be different for everybody but I'd probably go for the Hellraiser because I prefer the 81-7/85-7 set over the 707's but apart from that there isn't much in it.
