How does one choose a team to support?

[Matblack]

Well having enjoyed the rugby so much at the weekend I've decided to break with my tradition of not following team based sports and get myself a domestic rugby team. However I've never been in the position before, how does one secure oneself a team to support. I've never been a fan of 'distance fandom' supporting teams from the other end of the country because they are good just doesn't seem right. That leaves me with 3 rugby teams to choose from (London Irish are out of the picture).

Saracens
Wasps
Harlequins

Quins are technically closest and play at The Stoop in Twickenham, I like Wasps and Saracen's strips (both play in black). Wasps actually play out of High Wycombe which is a bit of a trek and Saras are a bit further round than Quins.

Its all rather complicated :/
