I've got sunday tall-t bars right now 8.7 tall, and I've been using them for an year or so, but they feel kinda not responsive enough for me, so im thinking of changing them. I'm about 180cm tall. I don't know much about the angles (backsweep upsweep) and why they matter, but might have an influence too. the tall-t has 12;4. So what bars should I get? Thanks
