Nice set up, and I'm sure they need to be where they are for necessity. Your method will certainly discourage the casual thief. But don't think they are theft-proof, an equipped thief could have both of them gone in about 15 seconds. A Metabo or Milwaukee cordless grinder with a diamond wheel will eat right through any anti-theft cable. The tighter the cable is, the easier it is to grind through. I saw my plumber friend cut through a 3/8" stainless anti-theft motorcycle cable in less than 5 seconds, using his cordless Metabo.
