MKS Alpha vs Toshi Double straps

hey i'm sorry to bring this thread back from the dead but i googled and that's what i found.
so basically i have to choose between the super fancy njs alpha sports (£80 on wiggle) and the super fancy toshis, which are sold in the shop here in town (something more than 80)

question is: is all that money really worth it? cause i bought some cheap double straps and i took them off after two days, no grip at all and i had to tighten them up again after almost every stop.
i'm choosing among those two because they are the easiest to get at the moment for me, but still, f*ing expensive.

and another thing is: is really a good idea to rock toshis on a commuter bike? i mean, straps can be stolen in less than 10 seconds, and when they are as worth as the wheelset i don't know if that can be a good idea to park the bike around for more than the above mentioned 10secs.

apart from that, what would you suggest among these two? maybe it's better to go for a third party?

My two pence, having tried double straps of a couple of varieties, metal clips, on mks sylvan pedals, on mtb pedals, double straps with plastic clips on bmx pedals, and horizontal straps on bmx pedals (JOL straps to be specific), and now clipless : Time ATACS, with carbon soled specialized mtb shoes.

If you are wanting to do any kind of trick riding Horizontal straps are where its at, maximum leverage/comfort/speed of release when it comes to bailing from or doing tricks, very durable, no fixings/fastenings/anything to break!

For commuting/speed/general bombing around, it doesn't get better than clipless, nothing compares....seriously nothing, not even the best double straps and clips in the world can touch a good clipless set-up, the performance increase is amazing, and if you are riding brakeless your braking ability jumps up ridiculously.
