Cartridge recommendations for Rega RB 1000


Am currently running a Gyro SE with HR power supply, RB 300 arm and Sumiko Bluepoint 2 cartridge. The rest of the system comprises : Phd Sutherland phono stage, CJ CT 5 pre, CJ LP70S power, Musical Fidelity KW 25 dac/trpt.,Quad 2905 speakers, with all Cardas Gold Reference cabling, Transparent power chords etc
Would greatly appreciate comments/advice regd. the RB 1000 arm with recommendations for a compatible cartridge. Am inclined largely on the basis of reviews/ advise from friends towards a Ortofon Kontrapunkt B, or Koetsu Black or maybe a Lyra Helikon. There is no way that I will get to audition any of the cartridges prior to purchase. Hence, the advice/views of A'goners is deeply appreciated.
Cheers

Many thanks for all the comments/advise. Have figured out that I need a new arm band which I have ordered along with a RB1000 from analogue seduction in UK.

Did consider the Techno arm. Its basically a moded RB 250/300. The RB 1000 is an update to the now discontinued RB900.A friend has the Gyro with the RB900 and is immensely happy.The the bulk of my audio decisions are based on friendly advice given the limited choices/brands available in my part of the world.
Cheers.
