When testing it's important how they feel. Ask yourself the question: "Will I have sour hands after a day's use? Will my hands getting tired quickly? Can I chance my hands in several positions during cycling?"
Last, but not least, the handle bars have to look good. Solid. Thorough. Reliable. Logical. Giving good grip.
Pen and ink.
I also plan to make at least four bigger drawings then I usually make. The first sketch is already in the making: it's going to be an Austin Healey 3000. The final result can be seen on my webshop, where you already can find four examples of black and white drawings of classic cars.
Furthermore I plan to make one or two paintings. Subjects are not yet chosen, but that won't be the problem. My main problem will be finding time to make all this stuff.
As much I like to read the stories and enjoy exploring the maps, best is to travel for yourself. But the usual obligations prevent that: job, kids attending school, lack of good travel gear.
Perhaps it's time to start first by orientating what you might need for travelling, for instance: a good bike.
