Locking wheel bolts. Aggravation!!

Sometimes I think my luck is cursed
The recently acquired winter wheels have been on for a while now, I got a flat tyre flag from the car Tuesday. I stopped and reinflated the nsf on the go, and got the car home, inflated again to check overnight and yes it was low again. Out with space saver, fit it and off to the tyre emporium. Not a puncture I was advised but the base of the (BMW) valve was leaking air and they had one, great, hassle saved or was it? The aluminium valve hex head immediately burred and they could not get it out. Off to the main dealer with wheel in hand.
I left it with them overnight and was pleased to get a call, wheel sorted no damage, sensor saved and valve replaced. £40.27 for a valve and labour. Swapped the wheels back again and using my pre-set 140 Nm BMW torque wrench I went diagonally and then rotationally on the bolts. Next thing I know is the wrench was on the ground via the wheel inflicting a large chip around the outer bolt hole, the BMW- McGuard tool rolling away and the machined area for the fancy Mc Guard locking system was laying on the ground having separated from the bolt.. I've now suffered a hefty knuckle thwack and the frustration of a damaged wheel.
Looking at the Mc.Guard bolt the machined area is a pseudo dummy, behind it the main bolt body has very fine splines in a recess which the machined pattern section is compression fitted into. I've hammered them back together and will buy a new set, as when I checked the other three wheels another bolt separated, thankfully with no wheel damage this time.
So replacement locking wheel bolt time, but Mc Guard again or the cheaper possibly better original BMW type with the coarse splines and nothing to break or separate?
