Yea, BL is great.... you will pretty much only be beat by a better driver.
I use orion 3600's and orion 4800's. I suggest the 3600's their faster with a 10.5.
anyway i have had my 2 4800's for almost a year and they still work great. I love lipo's.
I use orions but cannot comment on anything other then smc and trakpower. I would stick with orion in a heart beat but wouldn't suggest anything other then those 3.
The lrp sphere is a great BL speedo.
I say get back into it. Electric is easier then ever !
