Bass Clarinet to tenor trouble

hello, i have been playing tenor for about 4 months now for jazz. i have been playing bass clarinet for 6 years now, and i have recently tried clarinet and have had little trouble ajusting from bass to regular clarinet. tenor, however, is a different story.

My intonation on tenor is usually way off, and im almost always sharp in the upper register. I have tried holding a concert G on the mouthpeice, but i usually cant hold it. I still have difficutly getting low notes to sound, and when i do, it usually sounds harsh. Intonation and tone quality aside, i can play low Bb through high F sharp, and the G and D above that, although it is hard on the ears.

Other than my Embouchure issures, the sax fingurings are almost natural to me now, like clarinet. I can read fairly well, and anything i cant read i can usually work out. my main issue is the embrouchure. That, and learning how to play jazz.

i have been practicing tenor alot, the bari sax player next to me complemented my immense improvement since i started. I am mainly interested in sax for jazz, and in search of a good jazzy sound.

My bass clarinet is a Buffet Prestige, and i use a rovner dark lig and a grabner LB mouthpiece.
I have a black and silver cannonball tenor that i borrow from my school, although i discovered during inventory that we also have a Mk 6 tenor that has been overhauled at least once, once it returns from the shop for a few new pads i might try it again. Im currently using a Cannonball 5* mouthpiece that came with the horn, and im looking for an upgrade, especially after trying my friends old link (wow!) im usuing vandoran java 3 1/2s, and a rovner light lig.

any advice or suggestions or excersizes that might help would be greatly apreciated.

Edit: i forgot to mention, on bass clarinet, i play double lipped, when i started tenor, i forced myself to play single lipped. on reg clarinet, i also play single lipped, double just doesnt feel right to me
