to answer a couple questions. yes, i still very much love my roadster. it is a beast and it does have a very special tone that this mark will never achieve but let me say that this mini size should not full you with its power. the cleans are beautiful and the heaviness this thing can achieve is just wonderful. i'm currently working on a playthrough of this amp so i'll be sure to show it off
as far as the "too many options" comment i can understand but its very easy to find a likable setting once you spend some time with it. like right now i'm really loving the fat channel on channel 1 with a bit of gain pushing it slightly. and i love the mark 4 setting with the gain a bit low. it really is amazing. the 10watt and 25watt modes are very responsive and different. definitely 2 different flavors. i definitely like the high gain stuff at the 25watt but the cleans work great on both settings.
i've never used a full mark 5 so i can't really comment on a comparison but i hear its very good.
all in all this thing has HUGE balls for what it is and tons of options if thats your thing. although its very easy to set and forget.
