msd ignition ?

hello all, just wondering if there is anyone on here with experience of using the msd 6al ignition modual, i already use the mega blaster coil & kv85 leads and was thinking about upgrading the modual for even better ignition.
i am running 2l mk3 2e bottom end, twin 40 webers, any thoughts or comments on the msd 6al are welcome as i don't know if it is worth sticking my hand in my pocket to give msd £270.

ok since the previous posting i bought a second hand msd 7al2 ignition system. it plugs into existing wiring and seems to be doing the job well. the engine revs a lot smoother with the increased multi spark ignition. i will not be able to get everything perfect until i by a tach adaptor for the system and buy a timing light that does multispark ignitions. already i would recommend it if like me your running twin webers where the fuel doesn't atomize properly.
