New speedo

[Ross]

I looking for a new Speedo fro my DB1. Im running a Tekin RS at the moment with has been great but im looking to upgrade.

Now the short list is either a Tekin RS Pro,Orion R10 Pro or the SP Reventon Pro. The Orion and Tekin have been recommended but im not sure on the SP, i will mainly be running at Silverstone on there high grip track with a thunder power 7.5 motor will this speedo handle it OK. The spec's on the Tekin and Orion look good but the SP says its a 140amp, i know it will handle the 7.5 motor but my concern is that the high grip may cause it to thermal.

What do you think.

Cheers
Ross
