Roadmap to a Republican-controlled House

My readers probably all know that Republicans need a net gain of 39 seats to retake the House.  The following if my roadmap, showing the races the GOP needs to win to take a majority.  Open seats are in bold.  Seats with a freshman incumbent are italicized.  Seats with a sophomore incumbent are underlined.  

Republicans must win at least 20 of the following Democratic-held seats where they are currently favored to win:
(1) NY-29
(2) TN-6
(3) AR-2
(4) LA-3
(5) KS-3
(6) IN-8
(7) MD-1
(8) NM-2
(9) OH-1
(10) OH-15
(11) CO-4
(12) FL-24
(13) MS-1
(14) ND-AL
(15) NH-1
(16) NH-2
(17) WA-3
(18) AR-1
(19) IL-11
(20) TN-8
(21) TX-17
(22) FL-8
(23) MI-1
(24) PA-11
(25) VA-5

Republicans need to win at least 20 of the following Democrat-held seats that are generally regarded as toss-ups:
(1) MI-7
(2) OH-16
(3) PA-7
(4) WI-7
(5) FL-2
(6) NV-3
(7) NY-24
(8) VA-2
(9) IN-9
(10) SC-5
(11) WV-1
(12) IL-14
(13) SD-AL
(14) PA-3
(15) NC-8
(16) AZ-1
(17) AL-2
(18) AZ-5
(19) CA-11
(20) GA-8
(21) NY-19
(22) PA-10
(23) PA-8
(24) AZ-8
(25) IA-3

Depending on their success in securing the above seats, the Republicans will probably need to win 5-10 of the following Democrat-held seats where the Democrat is currently the favorite.

(1) OH-18
(2) TX-23
(3) WI-8
(4) ID-1
(5) MO-4
(6) NM-1
(7) OH-13
(8) VA-9
(9) CO-3
(10) MA-10
(11) NY-1
(12) NY-20
(13) NY-23
(14) OR-5
(15) PA-12
(16) IN-2
(17) KY-6
(18) NJ-3
(19) FL-22
(20) VA-11
(21) TN-4
(22) NY-13
(23) IL-17
(24) NC-11
(25) WA-2

Republicans probably won't need to win any of the following Democrat-held seats to secure a House majority, but any wins in this group will mean a GOP wave has developed.

(1) MI-9
(2) CA-47
(3) CT-4
(4) GA-2
(5) KY-3
(6) NY-25
(7) PA-17
(8) PA-4
(9) CO-7
(10) CT-5
(11) WI-3
(12) WV-3
(13) CA-18
(14) IL-8
(15) NC-2
(16) MN-1
(17) RI-1
(18) CA-20
(19) NJ-12
(20) NC-7
(21) OR-1
(22) ME-1
(23) ME-2
(24) AR-4
(25) GA-12

Republicans are expected to lose 3-4 GOP-held seats, obviously if Republican candidates pull off these races, it will decrease the number of Democrat-held seats the GOP must pick up.  The Republican-held seats in jeopardy are the following:
(1) LA-2
(2) DE-AL
(3) HI-1
(4) IL-10
