Based on the evidence I collected or I have collected

(1) I came up with the conclusion based on the evidence I collected.

(2) I came up with the conclusion based on the evidence I have collected.

Some of my non-native English speaking friends think (1) is grammatically correct because the verbs "came" and "collected" are both in the past tense. But, my other friends and I think (2) is grammatically OK if you use the present participle "have collected" even though "came" is in the past tense. The reason is that you might be using ALL the pieces of evidence that you have collected up until now.

What is your opinion? Thanks a lot.
