Thanks guys! I kinda like the 'suicide bars', when I first got the bike the levers were angled so that when I pulled on the lever it came right into the bar and stopped me dead, but I've taken the old tape off, took the bars off and cleaned them and put the levers back on, and now I'm noticing that they don't stop me completely because the levers don't come right into the bars anymore which I think is what Johnsqual was alluding to, I must've mounted the levers in a slightly different position on the curve to where they were previously.
I think I'll keep the suicide levers for now, I like to ride with my hands on the flat part of the bar and as I've just re-taped the bars I don't really want to replace the levers at the minute, the current ones work fine for what I need the bike for. I think for the time being I'll see if I can get some normal vertical hood and get my scalpel out!
