2 CB-Fly and cross tolerance with Lysergamides

[sin_is_synthetic]

I am planning a 6 day vacation coming up and I am bringing 30 mg 2cb -Fly and 300 ug ALD-52. Ive heard mixed things about the cross tolerance regarding Fly,some say there is and others say there is not.If I drop the 30 the first night, and then 5 days later try the ALD will there be a tolerance issue? 300's normally a high amount for me but if its going to feel like less Id go for it.
